Questions worth asking about Card Harbor.

Card Harbor is built for solo TCGplayer and ManaPool singles sellers with thousands of cards at home, a day job, and no staff. It fits sellers past TCGplayer's 51-order gate, where staged CSV imports are unlocked and pull sheets are already part of the week. It is not a POS, buylist, storefront, warehouse, or collector showcase tool: store platforms, ManaBox, or Collectr are better fits for those jobs.

Windows may show a "Windows protected your PC" notice the first time you run the installer. That's about the installer's age, not its safety. SmartScreen scores an installer by how many people have already run it cleanly, and Card Harbor is early access with a small crew of downloads so far. Microsoft no longer grants automatic reputation to EV certificates, so every publisher, signed or not, starts at zero and earns trust the same slow way we do.

No. Your card inventory, scan images, storage locations, and app settings live in a local SQLite database on your own computer, not on Card Harbor's servers. See the telemetry page for a line-by-line breakdown of exactly what is and isn't sent.

Be honest with yourself about what this is: Card Harbor's automation signs in to your own TCGplayer account, on your own machine, and performs the same actions you could perform yourself in the seller portal. It holds no API agreement or partnership with TCGplayer, and TCGplayer's own terms govern your account, including the right to limit, suspend, or terminate it at their discretion. Using automation carries that risk, the same risk any automated or scripted use of a platform carries. Read the full disclaimer in the Terms of Service before connecting an account.

If TCGplayer changes its platform or objects to automated access, Card Harbor may need to modify, limit, or disable the affected features, and doing so isn't a breach of the terms.

No. Card Harbor is a Windows desktop application that requires Windows 10 or later. Mac is not currently planned.

Mostly, after the first run. A fresh install syncs the card catalog once before the scanner can identify anything. From then on, scanning, inventory, and finding cards all keep working with no connection at all, since camera identification and storage run entirely inside the app. Anything that talks to a marketplace, pull sheets, publishing, repricing, and syncing, needs a connection.

No. Every scan runs at full quality: no meter, no monthly cap, and no top-ups to buy when a big buyout lands on your desk. Tools that meter high-quality scans are charging you to catalog your own cards; Card Harbor doesn't.

Yes. ManaPool is a second marketplace alongside TCGplayer: Card Harbor stores a ManaPool access token the same encrypted way it stores your TCGplayer session, and the fee and profit calculator covers both marketplaces' seller fees side by side. Turn on per-marketplace allocation and the oversell guarantee makes it structurally impossible to sell the same physical copy on both marketplaces at once.

TCGplayer and ManaPool each charge their own commission and payment-processing fees on every sale, and those rates change from time to time, so restating numbers here would just go stale. Use the fee and profit calculator to plug in a sale price and see net proceeds, profit, and margin for either marketplace.

Not right now. Card Harbor is not currently available for download. This site stays up as a record of what the app does, alongside the roadmap and the changelog of what shipped.

Pokemon cards are on the roadmap's "Coming next" list, along with sealed product and supplies, and faster scanning. The groundwork is already underway, so Pokemon inventory will scan, store, and publish the same way Magic inventory does today. The roadmap deliberately publishes no dates, only the order things are landing in.
